ATTOF NEY CLAIR F. DRURY, OF DAVENPORT, IOWA,

FOUNTAIN-BRUSH.

Application led .Tune 19, 1918.

To all whom it may concern Be it known that I, CLAIR F. DRURY, a citizen of the United States, residing at Davenport. in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Fountain-Brushes, of which the following is a specification.

This invention relates generally to brushes and particularly to fountain brushes and has for its primary object to provide a fountain tooth brush in which the head and handle of the brush are separable, the latter being made hollowto receive aI carton of tooth paste and containing means for forcing this paste through the handle and also through connected openings therefrom in the biush head and into the bristles of the brush.

W'ith these objects in View, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts, all as will be described'more fully hereinafter, particularly pointed out in the claim, and illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of the brush complete.

Fig. 2 is a vertical, longitudinal sectional view of the same.

Fig. 3 is a top view of the brush head detached.

Fig. 4 is an underside view of the connecting member between the brush head and the brush handle.

Figs. 5 and 6 are cross sections on the lines 5-5 and 6-6 respectively of Fig. 2, taken through the brush headHiand Fig. 7 is a cross sectional view on the line 7 -7 of Fig. 2 taken through the handle.

Fig. 8 is a side view, and

Fig. 9 is a cross Sectional view of the paste carton.

Fig. l0 is an enlarged sectional View taken on the line 10-10 of Fig. 2.

In the drawings, 10 indicates the brush head and 11 the handle of the brush, these two -parts being connected together in a manner to be described which will permit them to be readily taken apart and cleaned as circumstances require. The brush head 10 made of bone, ivory, celluloid or other material will be made of any shape and size desired, but in the present instance, the brush being intended for a' tooth brush, the

Specification of Letters Patent. Patented Sept. 30, 1919.

Serial No. 240,826.

length and width of the head is limited as shown and provided on one side at each end with bunches of bristles 12. Preferably the center of the brush head has the bristles omitted to provide room for a longitudinal series of perforations 13 through which the tooth paste reaches the brush. The top of the brush head 10 or side opposite that containing the bristles is formed with a groove 11 extending from one end of the brush head toward the opposite end for a distance greater than one-half the length of the brush head. This groove has its side edges undercut to engage with the beveled flange 16 on the connecting member 17 that joins the brush head 10 with the handle 11. They erforations 13 extend through the brush'head 10 into the groove 14 and are countersunk or enlarged at this end to provide ready entrance for the tooth paste into said perforations.

The connecting member 17 between the handle and the brush head comprises generally a rectangular plate 18 having beveled edges 16 to engage the inclined edges of the groove 14 and a hollow conical stem 20 projecting rearwardly from the upper surface of the plate 18. The stem 20 at its forward end where it joins the plate 18 opens into a slot 21 in the plate 18 which when in position on the brush head 10 is immediately above the pcrforations 13, and it is throu h this slot 21 that the paste passes from t e handle to the brush head. Two spring tongues 22 are secured at one end to the plate and project rearwardly at an angle, their other ends having semi-circular studs 23 that project outwardly and engage depressions 24 formed in the walls of the groove 14, near the rear end of the brush head 10. By means of the above described fastening devices, the connecting member 17 holds the brush head securely 1n place and prevents its slipping forward and becoming out of place or lost. The rear end of the member 1T is finished with a threaded stud 25 upon which one end of the handle 11 is screwed; the opposite end of the handle which is of tubular formation, is closed by a cap 26 exteriorly screwed on the handle and having an opening through its axial center for a screw stem 27 which rotates freely in the cap 26 when turned by a button 28 on the outer side of the cap. The

stem 27 dxtends the full length of the handle 11 and is threaded from end to end for a pressure disk 29, which will be fed from end to end of the handle when the screw stem is urned.

The tooth paste used in connection Wlth this brush is preferably furnished 1n celluloid tubes 30, open at both ends and provided with u longitudinally extending rib 31 on the inner side of the tube which enters a notch 32 in the disk 29 and prevents the latter rotating when the Stem 27 is turned.

A brush such as described iseonvenient and thoroughly sanitary as the same may be taken apart and cleaned With little trouble and when necessary a new tube of paste can be placed in the handle With little trouble and all further consideration as to the whereabouts of tooth paste has been eliminated. I

The foregoing descrlption and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, Inaterials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claim.

Ilaving thusfully described my invention, what I claim as new and desire to secure by Letters Patent, is: A

In a fountain brush, the combination with -a brush head whose back plate is provided with perforations at its mid-length and a groove in its rear face extending from one end beyond said perforations and having its walls undercut and notched near the open end of the groove; of a tubular handle, ejecting' means therein, and a connector between the handle and brush head, the lower'plate of the connector having its edges beveled to engage the undercut walls of said groove and its body slotted at a point to overlie said perforations in the brush head, and springr tongues on said plate adapted to enter said notches, for the purpose set forth.

In testimony whereof I affix my signature in presence of tWo Witnesses.

CLAIR F. DRURY.
